So, it would've jammed just short of being fully chambered.
The disconnector should have prevented the gun from firing.
An alternate explanation is that it was an overload and the case head blew out. But, if that happened, typically the magazine is blown out, the grips are splintered, and you might have a hand injury.
I "second" your idea to cull and discard other people's fired brass from your own Starline brass.
You should have the disconnector evaluated. If it was defective or worn, that could be part of the problem. But, a full evaluation of the whole pistol is likely a good idea.

The disconnector was replaced along with the hammer and sear towards the end of 2017 when the action was worked on.
While I was not using a holster, I was applying the safety lowering the pistol to an approximate holster position and acting as if I was drawing the gun for each shot (it is one of my standard practice routines). I doubt the safety would have engaged if the slide was not fully in battery.
The only other explanation I can think of is the bullet getting pushed further into the case when it hit the feed ramp, but then it should have failed to feed into the chamber.
